My invention relates to humidifiers. 1t is the object of my invention toprovide a humidifier which will thoroughly incorporate moisture withincoming air to be delivered to an enclosure gV and which willthoroughly scrub excess moisture and dirt in the air from the air priorto delivery to the fans and thence into the enclosure. 1

In particular, it is the object of my invention to provide a knock-downstructure which can be quickly disassembled and assembled so that thestructure can be carried in its several parts through an ordinarytwo-foot six-inch door, such as in cellars of dwellings, where myinvention is to be primarily used in connection with hot air heatingsystems.

The present difficulty with humidiiers of various types is that theyhave to be completely built Within the cellar of the building and mustbe fabricated at the point where they are used, thereby preventing readyreplacement, repair and adjustment, as well as cleaning, and may causeexcess costs due to the fact that the humidier must be built by hand inrestricted places in cellars.

My invention, to the contrary, incorporates a separable structure intovarious component parts, in addition to providing novel features thathave additional advantages of construction and operation.

Referring' to the drawings, Figure 1 is a top plan view.

Figure 2 is a side elevation.

Figure 3 is an end elevation of the outgoing or fan end of thehumidifier.

Figure 4 is an end elevation of the inlet end where the humidifiersprays are located.

Figure 5 is a section on the line 5 5 of Figure 1.

Figure 6 is a section on the line 6-6 of Figure 5.

Referring to the drawings in detail, 1 indicates the inlet air openingthrough which incoming air is delivered over the water sprays 2 suppliedby the water pipes 3. The sprays are directed in the direct-ion of theair flow. They, therefore, do not impede the air flow but assist it. Theair passes through the sprays rather than have the sprays driven throughthe air. As the sprays .overlap due to the expansion of the spray conesupon the release of'water through the sprays, the air passes through aplurality ofthe sprays in a major portion of the interior of thehumidifying chamber t. The bottom of this humidifying chamber isprovided with two sections 5 and 6 to form a trough, the base of whichis at 7, from which the liquid may be removed through the aperture 8.The sprays are directed not only7 in the direction of the 60 airmovement but also towards the scrubber plates 9 so that whatever burdenof free moisture is incorporated in the air vwill be immediatelyscrubbed from the air by the contact with the plates 9 which areprovided with 65 angular portions 10 to catch the free moisture on theplates and to convey that moisture downwardly by gravity where themoisture runs 0E through apertures 11 in the false botl tom 12 above thetilted bottom 13 which con- 70 veys the free water through the aperture14 onto the bottom 6 and thence out through the aperture 8. Y

The top of the humidifier chamber is provided with a box enclosure 15telescopically 75 mounted as at 16 within the top of the humidifierchamber. The flange 17 of this box rests upon the flange 18 on top ofthe humidifier chamber. When the closure is removed the scrubber can beinserted through the opening closed thereby. p

Detachable cover members 18a having flanges 19 are mounted within thetop ofthe box 15 and rest within the inwardly turned trough'20 aroundthe upper margin of the 85 boX 15. The covers 18 may be made either withthe handles 21 or without them. Any number of these tight fitting covershaving depending flanges 19 `may be Iemployed to close the top of thehumidifier chamber.

It will be further noted that the scrubber plates 9 are mounted at theirlower ends upon the false bottom 12 and are provided with a cover 21aand side walls21,

Thus the entire group of scrubber plates, top and bottom plates, are aunit. This unit is slidably ymounted within the passageway formedby theside walls 22, bottom 13 and top 23 leading from the humidifier chamber4. This passageway constitutes the scrubber 10 chamber 24. It is thuspossible to remove the entire scrubber from the scrubber chamber forcleaning, adjustment and repair, and take it out of the top of thehumidifier chamber; and it is possible to remove the box 15 to reducethe dimensions of the humidifier chamber or to let the box remain inposition and remove one or more of the covers 18.

It will be further noted that as a part of the facility of disassemblyand assembly coming from the use of my particular construction, Iprovide for the telescopic engagement of the outlet and of the scrubberchamber with the inlet end of the fan chamber. A collar 25 receives theinner end 26 of the scrubber chamber, which is limited in its inwardmovement by the angular abutment 27 engaging the angulaiabutment 2S onthe respcctive scrubber chamber and fan chamber en s.

The fan chamber is formed of a bottom wall 29, a top wall 30 and sidewalls 3l. Journaled in the side walls 31 is a fan shaft 32 having thefans 33 mounted thereon. These fans are driven by a pulley 34, belt 35and motor 36.

The outlet openings 37 from the fan are normally closed by theself-closing dampers 38 which are opened by the pressure of the air whenthe fan is in operation.

It is to be further noted in this construction that all of the excesswater tends to run backwardly counter to the direction of the air sothat the air passes over the surface of the water for furtherincorporation of the moisture with the air.

It will be further noted that the scrubber casing is limited in itsinward movement by the shoulder 40 on the outlet end of the scrubberchamber. o

I desire to comprehend within my invention such modifications as may beembraced within my claims and the scope of my invention.

Having thus fully described my invention, what I claim is new and desireto secure by Letters Patent, is:

l. In combination, a humidifier chamber, a. scrubber chamber connectedto the humidifier chamber, a scrubber and scrubber frame slidablymounted in said scrubber chamber and means for causing the entry andremoval of the scrubber from the scrubber chamber through saidhumidifier chamber, said humidifier chamber having a detachable coverclosing, an opening through which said scrubber can be introduced andremoved and an air inlet opening in which water spray means are located.

2. In combination, a humidifier chamber having an air inlet and an airoutlet, a trough-like bottom in said humidifier chamber, a scrubberchamber having av tapered bottom communicating with the trough-likebottom of the humidifier, a detachable scrubber having a top, side wallsand a horizontal bottom wall perforated to allow moisture to escape anda plurality of spaced scrubber plates interposed therebetween andsupported on the perforated bottom above the tapered bottom and thesloping bottom of the scrubber chamber; and water sprays adjacent theair inlet opening of the humidier chamber having their sprays directedin the same direction as the passage of air therethrough towards thescrubber in the scrubber chamber.

3. In combination, a humidifier chamber having an air inlet opening, anair outlet opening and a top opening, a box member open at the top andbottom mounted in said top opening, a detachable cover for said box,water sprays beneath said box and detachable cover in the path of theincoming air through the air inlet opening, a scrubber in the air outletopening from the humidifier chamber,

and means of conveying surplus moisture from the scrubber back into thebottom of the humidifier chamber.

In testimony whereof I affix my signature.

FRANK J. HOERSTING.
